I agree with coleopterist that this is an error; but the interesting question remains: What did the author of this post mean by characterizing a pimp as ‘loyal’?
I can’t credit the UD definition offered by MonsterMushroom, which strikes me as a promotion for or tongue-in-cheek appreciation of one of several bands called “The Loyals” or with “Loyal” in their name.
I suspect the author is harkening back to a fairly well-known piece from the gangsta rap genre, “Loyal to the Game”, the title song (represented by two mixes) from a Tupac Shakur album posthumously released in 2004. The singer represents himself as a long-time, hardened criminal who supports his family and his extravagant lifestyle by violence, who fears no one and defies both the authorities and his rivals, and who demands respect for the identity he has achieved: “the struggle that I'm from is attached to my name”.
I do my thing respect my hustle I ain't playin' (Nigga I'm loyal to the game)
You get in my way and I cock and pop that thing (Man I'm loyal to the game)
If you know what I know then you know I ain't playin' (I'm loyal to the game)
Nigga get in my way and I’ll blow out your brain
The tracks are available on YouTube, and full lyrics may be read here.
I suggest that the author means readers to understand loyal as something like “a ‘made’ man, swaggeringly proud of his amorality”.
It is possible, too, that the use here is colored by chat around the popular online game Pimp War, in which players undertake the role of Pimp. The Pimp is depicted as very like 2Pac’s hero— fundamentally a loner, seeking to achieve invulnerability in a viciously Darwinian underworld—but to reach the top must form alliances with other Pimps. Loyalty to one’s partners (or at least the appearance of loyalty) is essential to building these alliances, as may be seen from the appeals:
If you pimp daily, experienced, and loyal to your fellow alliance members message me or Frog(#2154) and after we check your stats we'll send you a invite.
I ROLL WIT ALOT OF GOOD CREWS ILL ROLL WIT ANYONE REALLY THAT HAS SUMTHIN GOOD GOIN ECXEPT IN CRACKO I AM A TRU LOYAL CANADIAN-PIMP NO MATTA WHAT BUT IF U NEED ARMS IN ANOTHER GAME HALLA AT YA BOY 1
So loyal also implies “worthy of alliance”.
